Service bulletin TSB 414

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Following notification from Spartan Motors Inc., Newmar has determined that a potential hazard exists in certain motor homes. On certain vehicles equipped with a Wabco quick release with double check valves, used to control park/spring brake application, the valve may leak internally. This could cause unintended partial or full park/spring brake application, which could affect service brake function and increase the risk of a crash causing injury and/or damage to property. NHTSA # 15V-061, TC# 2015-041
